The influence of particle-associated spacetime curvature on particle dynamics weakens at smaller particle mass scales, leading to an acceleration of effective state evolution characterized by Teff, which is taken to be bounded by the Planck time as a theoretical lower limit within this framework. At sufficiently low masses, the effect of particle-bound transient wormholes becomes significant, preventing further meaningful subdivision of particles and offering a geometric interpretation of quantum nonlocality.Wormhole influence increases as particle mass decreases, while classical particle-associated curvature increases with mass, representing complementary aspects of the same physical transition, with a crossover region determining which influence dominates. For particles with masses below this region, particle-bound transient wormhole effects emerge progressively and the influence of particle-associated curvature is correspondingly subdued; above the region, the reverse holds, with curvature becoming dominant and wormhole effects diminishing.Related permanent archive (Zenodo):DOI: https://doi.org/10.5281/zenodo.17979116Supplementary explanatory website:https://researchlogic.org
